Installing the project

To install the project, first clone the repo and run the following on the directory where you save the project:

npm install

Or if you're using yarn:

yarn install

After you run the above command, create a key.json file in the directory. This key.json file is your firebase-admin key. Generate private key from your firebase project and paste the value inside the key.json file.

Next, create .env.remotenode file. This .env.remotenode file contains the contract address you want to listen to, the provider you're using, and the firebase collection name. You can add more .env file and name it as your needs, don't forget to update package.json script if you're adding more .env files. The .env file format looks like this:

CONTRACT_ADDRESS=<contract_address_here>
PROVIDER=<provider you are using, you can use http:// provider or ws:// provider>
COLLECTION=<the name of firebase collection you want to use>

To start the logger, run the following:

npm run start-remotenode

Or using yarn:

yarn start-remotenode

You can tweak the package.json script if you're using different .env file name. This project use custom-env library to manage environment variables.
